In recent years, CMOS power amplifiers (PAs) have made significant inroads into the cost-sensitive GSM GPRS and 3G markets. While this has taken some market share away from traditional GaAs PAs, the f...

It is one of the mobile industry's dirty secrets, but nearly all of today's 4G handsets do not transmit at full power. Instead, 4G handset manufacturers have been producing "half-power handsets," due ...

Jeremy Hendy, VP Marketing at Nujira describes how envelope tracking technology can be used to create RF power amplifiers where the characteristics are defined by software.

We are on the cusp of a major shift in battery technology for mobile handsets as Li-ion batteries reach the limits of their capabilities and new chemistries emerge to replace them. As more energy need...

Recently, much has been made of the prospect of increased competition for traditional GaAs PAs from CMOS alternatives. Interest in this has been piqued by the release of products such as the Qualcomm ...

Envelope Tracking (ET) is reapidly becoming a standard component in the RF front end of FD-LTE handsets. Conversely, some have suggested that ET will not be required for handsets on TD-LTE networks. N...

With widespread adoption this year, mobile device manufacturers are waking up to the potential of ET. It’s clear to see that whether as a standalone chip, integrated with a CMOS PA, or ultimately into the cellular chipset, ET will rapidly become a critical enabling technology for the next generation of high data rate wireless communications.
